IMPROVEMENT IN VENTILATORS.

Specification forming part of Letters Patent No. 112,190, dated February2S, 1871.

To all whom it may concern: Y

Be it known that we, DANIEL M. SPROGLE and JOSEPH E: DIGKSON, both ofAnnapolis, in the county of Anne Arundel and State of Maryland, havejointly invented an Improvement in Ventilation and Warming, being a new,improved, and useful mode of producing pure moist air, either warm orhot moist air, or cool moist air, for ventilating, supplying hot-airchambers, warming, and other purposes; and we do hereby declare that thefollowing is a full and exact description ofthe same, suiiicient toenable others skilled in the art or science to which our jointinventionappertains to understand, apply, and use our joint invention, referencebeing had to the accompanying drawing, which makes part of thisspecilication.

Like letters of reference indicate like parts in the several gures.

The nature or' our joint invention consist in, first, the production ofpure warm or hot moist air for ventilating, warming, and other purposesby combining, in the manner hereinafter described, the mode of passingair, heated artificially or otherwise, through pipes or ilues fromhot-air chambers or from other sources of heat, with the method ofrendering air moist by means of exposing a current of air to themoisture supplied by minute jets of Water or spray, which combination iseffected in the following new, improved, and useful mode.

Figure l, A represents a pipe or ilue ot' any suitable materials,through which a current of warm or hot air is caused to pass from thehotair chamber K, or from any other source of warm or hot air. Drepresents a tank or chamber, of any suitable material or shape, and soconstructed that an aperture may be formed for the purpose of cleaningit out by removing the cap or cover a., which tank or chamber D isconnected with the pipe or flue E in such a manner that when illed withwater in any convenient way, either directly from another vessel or bymeans of the water-pipe F, which is made of any suitable material andfurnished with the regulating-cock Gr, it will gradually discharge thewater into the pipe or flue E, either through holes alone perforated inthat which forms the bottom of the tank or chamber D or through holes inwhich small tubes are inserted at the proper angle or angles, in

the form of many minute jets of water or spray, which spray is broughtinto immediate contact with a current of warm or hot air, which isconducted by the pipe or flue E either directly from the sameair-chamber as the current of warm or hot air conducted by the main pipeor flue A, or from the main pipe or lue A itself, the pipe or flue Ebeing for this purpose connected with the main pipe or iue A at theproper angle, and at any convenient or advantageous point, or from anyother source of heat.

The current of warm or hot air, becoming charged or saturated withmoisture by being thus brought into contact with the many jets of wateror spray proceeding in the manner described from the tank or chamber D,rushes onward through the pipe or ue E to the similar tank or chamber H,in which the excess of moisture is collected, and by the current oi' airis forced through either holes alone perfo rated in that which forms thebottom of the tank or chamber H, or through holes in which tubes areinserted at the proper angle or angies, and discharged into the mainpipe or iiue A at that point which is most convenient or advantageous,where the moisture in the form of spray is again brought, together withthe air surcharged with moisture, into immediate contact with a currentof warm or hot air-viz., the current which is passing through the mainpipe or tlue A, and by which the moisture is still further and morethoroughly taken up by absorption or evaporation, or is otherwisedi'used.

The excess of moisture is collected in the tank, chamber, or pocket I,connected in the proper manner with the main pipe or ilue A on the underside, and at any point in the main pipe or flue A most convenient oradvantageous, and is discharged through the waterpipe J, which is madeof any suit-able material and furnished with the cock L, into thechamber N, in which the water -pipe J terminates within the hot-airchamber K,

The chamber N, being similar in material, shape, and construction to thetank or chamber D, discharges the moisture within the hotair chamber Kinthe form of jets of water or spray, to which jets of water or spray thewarm or hot air in the hot-air chamberKis exposed, and thereby in somedegree rendered moist.

The excess of moisture from the jets of Water or spray proceeding in themanner described from the chamber N is collected in the open vessel,tank, or reservoir M, placed within the hot-air chamber' K, and in theproper location with reference to the chamber N.

And the nature of our invention consists,

secondly, in the production. of pure, cool,

:moist air for Ventilating, supplying hot-air I chambers, and for otherpurposes by combining, in the mode hereafter described, the method ofobtaining` cool air by means of passing a pipe or iiue, through which acurrent of air is caused to pass by the use of a blowing-V fan or byother means, into and through a well, tank, ci stern, or chamber, inwhich the current of air, as it passes through the pipe or flue, issubjected to the cooling agency of cold water either in a body or in theform of jets, or streams, or ice, or both water and ice contained in thewell, tank, cistern, or chamber, and to which the surface of the pipe orue conducting the current of air is therein exposed, with the method ofrendering air moist by means of exposing a current of air to themoisture.

supplied by minute jets of water or spray, which combination is effectedin the following new, improved, and useful mode:

Fig. 2, A represents a pipe or iiue of any suitable material, throughwhich a current or air is caused to pass by the use of the blowingfan Bor by other means, which pipe or flue A is passed into and through thewell, tank, cistern, or chamber C, in which the surface of the pipe orflue A conducting the current of air is exposed to the cooling agency ofcold water either in a body or lin the form of jets, or streams, or ice,or both water and ice, thus rendering the air cool as it passes throughthe vpipe or iiue A.

' D represents a tank or chamber of any suitable material and shape, andso constructed that an aperture may be formed; for the purpose ofcleaning it out, by removing the cap or cover d, which tank or chamber Dis connected with the pipe or flue E in such a man* ner that when filledwith water in any convenient way, either directly from another vessel orby means of the Water-pipe F, which is made of any suitable material andfurnished with the regulating-cock G, it will gradually discharge thewater into the pipe or liue E, either through holes alone perforated inthat which forms the bottom of the tank or chamber D, or through holesin which small tubes are vinserted at the proper angle or angles, in theform of many minute jets of Water or spray, which spray is brought intoimmediate contact with a current of air, which is conducted by the pipeor flue E either directly from the same air-chamber as the current ofair conducted by the main pipe or iiue A, or from the main pipe or flueitself, the pipe or flue E being for this purpose connected with themain pipe or iiue A at the proper angle, and

'at any convenient or advantageous point, or

from any other source. I

The current of air, becoming charged or saturated With moisture by beingthus brought into contact With the many jets of water or sprayproceeding in the manner described from the tank or chamber D, rushesonward through the pipe or flue E to the similar tank or chamber H, inwhich the excess of moisture is collected, and by the current of air isforced through either holes alone perforated in that which forms thebottom of the tank or chamber H, or through holes in which tubes areinserted at the proper angle or angles, and discharged into the mainpipe or flue A at that point which is most convenient or advantageous,Where the moisture in the form of spray is again brought together withthe air surcharged With moisture into immediate contact with a currentof air-viz., the current which is passing through the main pipe or4 flueA-and by which the moisture is still further and more thoroughly takenup by ab sorption, or is otherwise diffused.

The excess of moisture is collected in the tank, chamber, or pocket I,connected in the proper manner with the main pipe or iiue A 011y theunder side, and at any point in the main pipe or flue A most convenientor advantageous, and discharged through the waterpipe J, which is madeof any suitable material and furnished with the cock L, into the well,tank, cistern, or chamber, or elsewhere, as may be desired.

What we claim as our joint invention, and desire to secure by LettersPatent, is-- l. The chamber D, constructed as described, and combinedwith a pipe or flue used for introducing air into buildings, chambers,or apartments, substantially as and for the purposes set forth.

2. The chamber D, constructed as described, and combined with the pipeor iiue A by means of the pipe or Hue E, either alone or in connectionwith the tank or chamber H, substantially as and for the purposes setforth.

3. The pocket I, combined, as described, with the pipe or flue A and thewater-pipe J, substantially as and for the purposes set forth.

4. The system of pipes, iiues, and chambers consisting of the water-pipeF, the chamber D, the iiue E, the tank or chamber H, the iiue A, thepocket I, the water-pipe J, and the tank or reservoir M, for the purposeof producing pure warm or hot moist air, or pure cool moist air, forVentilating, warmin g, and supplying hot-air chambers, substantially asherein set forth.
